The backward scattering characteristic of the jet engine nozzle is one of the most challenging problem in applied electromagnetics. Radar cross section (RCS) data of a double S-shaped nozzle (DSN) with and without radar absorbing material (RAM) were measured in the microwave chamber using stepping test system. The experiment results show that S-shaped structure has a certain effect on the backwards scattering characteristics. Coating RAM can reduce the RCS of DSN effectively.
